摘要： 四溴双酚A(TBBPA)作为一种被广泛使用的溴代阻燃剂，在环境中广泛存在．从活性污泥中筛选出一株TBBPA的好氧降解菌，经16S rDNA测序鉴定为假单胞菌属，命名为Pseudomonas sp.JDT.该菌在40天内对TBBPA的脱溴率为12.9%.外加碳源能够促进该菌对TBBPA的矿化，且低浓度酵母提取物的促进作用高于葡萄糖和高浓度酵母提取物．利用14C示踪技术，在持续加有外来碳源的纯菌培养体系中测定JDT对TBBPA的降解，发现18.5天后TBBPA的矿化率为2.7%，并检测到两种极性代谢产物，分别占有机可提取部分总放射性量的11.2%和47.2%.Pseudomonas sp.JDT可以作为研究环境中TBBPA微生物降解途径的实验材料．
